Mouse Interleukin-6 Recombinant



SKU: RKP08505 Tags: , , , ,


Optimized DNA sequence encoding Mouse Interleukin-6 mature chain was expressed in Escherichia Coli.
Molecular weight
Native Mouse Interleukin-6, generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 22kDa. Recombinant IL-6 is a monomer protein consisting of 122 amino acid residue subunits, and migrates as an approximately 22kDa protein under non-reducing and reducing conditions in SDS-PAGE.
>97%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) determined by the dose-dependent proliferation of murineTD1 cells, was found to be <.01 ng/ml cells was found to be in the range ofx108U/mg.
Protein Sequence
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Recombinant Interleukin-6 was lyophilized from a 0.2 μm filtered PBS solution.
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at2° -8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
